Unanswered: Problem with toolbar overflow

I'm trying to create an icon only toolbar that supports overflow. However, I've run into two problems when the overflow is triggered:

1) The items in the overflow menu have an icon, but no text. This is expected since I'm just specifying an icon, but how can I have text that displays in just overflow mode?
2) My toolbar buttons are created with scale: medium. The overflow menu wants to use icons that are appropriate to a scale: small button. How can I either bump up the size of the icons or specify different icons of the appropriate size to the overflow menu?
